JOHN F. NOLAN, OF CHICAGO, ILLINOIS.

JOINING-TABLE.

Application filed July 29, 1907.

Specification of Letters Patent.

To all whom it may concern:

Be it known that I, J OHN F. NOLAN, a citi- Zen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in J oining-Tables,. of which the following is a specification.

This invention is a revolving joining table for assembling mold parts, and is particularly useful in connection with the assembly of core boxes, in which the half cores are molded in half boxes, and the halves are afterwards united to form the complete cores.

The object of the invention is to form a table on which the halves or parts of the core boxes may be conveniently supported and brought together to produce the complete cores.

The table will conveniently be placed beside or opposite a core molding machine, and it is rotatable so that either side may be turned to receive the half boxes or sections, which are afterwards united, as stated.

The invention is illustrated in the accompanying drawings in which Figure 1 is'a top plan view of the machine. Fig. 2 is a side elevation. Fig. 3 is a detail in section.

In the drawings, 1 indicates a stand which may be bolted to the floor at the bottom, and which has a circular disk or flange 2 at the top, having therein a ring groove 2*. A flanged plate 3 fits upon the top of the stand and laps the side thereof, and has a rib 4 which fits in the groove 2*: Bearing balls 17 are placed within the groove, for the rib to run on. A bottom ring plate 5 is bolted to the top plate 3, and projects under the extended part of the flange 2. By this means the table top is held in lace on the stand without any possibility of falling therefrom, and the table is also free to rotate on said stand.

Angle-iron blocks or braces 6 are bolted to the revolving table above described, and these blocks assist in supporting the opposite outwardly extending arms 7 which are bolted thereto and which form the main supports or bed of the table.

8 and 9 are hinge members. The former are fastened to the arms 7 by bolts 8 which are adjustable in a series of holes in the arms 7 to bring the hinged members closer together or farther apart, said members being arranged opposite to each other on each side of the middle of the table. The opposite hinge members 9 are connected to the members 8 by means of the pintles or rods 9, which extend across the table. Each of the members 9 has a projecting shoulder 9 which serves to support the core boxes when they are raised to upright position. The swinging leaves or arms 10 are bolted to the hinge members 9, and said arms when let down rest upon the bolts 11. The arms are spaced a art by cross rods 12 and 13, the latter of w ich carry swinging props 14 which normally hang down between the side pieces 7 of the bed or frame.

To hold each leaf 10 in any position in which it may be set, a latch 15 is provided, having a loop extending around the brace 14 and a point adapted to engage in one of a series of notches 14 in the props 14. The latch 15 is carried by a cross rod 16 which may be turned and operated by a handle 16 at the end thereof. By manipulating the handle 16 the catch may be engaged or disengaged.

To operate the table and join core box halves, the half boxes are deposited on each leaf or pair of arms 10 in turn, and these leavesor arms are then lifted to upright po sition, causing the core boxes to meet. The hinge members 8 are first adjusted the proper distance apart to produce this effect. When the core boxes are joined they fit and are held together by suitable dowels. hen the boxes are joined both halves are brought down on one side, and the top or cope half is removed and core driers placed thereon. The leaf is then brought up until the associated core boxes meet the other or opposite leaf, on which they are again let down, which operation brings the drag on top. This is then removed and the cores are ready to be put into an oven to be dried.

It will be seen that the leaves 10 can be swung either way, and they act first to bring the halves together to join the same, after which the Whole core boxes can be laid down fiat first on one side and then on the other.

The invention avoids a large amount of carriage and hand labor, and will be found distinctly useful for the purpose intended.

I claim:

1. A joining table comprising a rotary bed, and vertically swinging leaves hinged thereto opposite to each other and having means to support mold parts, and adapted to swing up toward each other to join said parts.

2. The combination of a stand having a circular head with a groove on top, and a bed or top frame rotatable upon said head and having a rib in said groove, and leaves hinged to said bed, to swing vertically toward and from eachother:

3. A oining table comprising a bed, vertically-swinging leaves hinged thereto and arranged to swing to upright position opposite each other, and props between the leaves and the bed to sustain the former in raised position.

4. A joining table comprising a stand, a plate rotatably mounted thereon, horizontal arms projecting oppositely from the plate,

vertically swinging mold-part supports hinged to said arms, notched props depending from each of said supports between the arms, and latches supported between said arms and having operating handles at the side of the table and arranged to engage the notches to hold the supports as desired.

In testimony whereof I aflix my signature, in presence of two witnesses.

JOHN F. NOLAN.
